There were two murders in the commissary, the deceased was a man and a woman, and the time of death was less than two hours, but the murder weapon was a mystery.

The wound was a round blood hole the size of a small thumb, as if someone had stabbed a hole with his finger, and Li Meng suspected that the murder weapon was a hidden weapon.

Although the hidden weapon sounds ridiculous, it is also the most plausible explanation at the moment.

After all, the murder weapon is still in the heart of the deceased.

Ren Qiushi and Zeng Lan worked together to turn over the male corpse lying on the ground, and the blood had already stained the clothes on his chest. Ren Qiushi untied the clothes on the deceased's body, and a bloody hole like a woman's corpse appeared in front of all of us.

The wound was also located in the heart of the deceased's left chest.

The wounds on the bodies of the two deceased were identical, and after careful wound comparison, it was found that the wounds on the two deceased were also the same size, and the skin and muscles of the wounds also showed no traces of valgus.

This shows that the two deceased were committed by the same murderer with the same weapon.

Moreover, the murder weapon that killed the man must have remained in the man's body.

"Martial arts master!" I sighed, and slowly accepted the secret weapon in the martial arts novel mentioned by Li Meng.

"What kind of martial arts master, this kind of launcher is very common, and it is the simplest kinetic energy device, such as a small crossbow device, which can cause this kind of wound and keep the sharp weapon in the body." Ren Qiushi explained to us seriously.

It seems that he is now in a state of work, and he looks unsmiling and cold. In other words, he won't be the same as Chu Liang, he is also a split personality, right?

There was a great similarity between the two bodies, and the medical examiner took both bodies back to the forensic department for autopsy.

"I ask the dead, you catch the dead." After Ren Qiushi sorted out the toolbox, he stood up and said to me.

"Okay, I'll wait for your autopsy report." I put away my smile and said to him seriously.

The forensic doctor left the scene, and the scene was handed over to the serious crime team and technical team.

"There was no trace of a fight at the scene, and no property was found, so the nature of the case should be vendetta." Jiang Tingbai carefully inspected the supermarket and said to us.

"It could also be a love killing." Li Meng said suddenly.

She is right, we, as criminal police, cannot let go of any possibility, even if the probability of existence is very small.

"Today is Halloween, there are people outside, and the scene of the crime is a supermarket, isn't the murderer afraid of being found when the murder is committed?" Lin Zifan looked at the crowd outside, frowned, and said.

"Judging from the wounds of the deceased, an automatic weapon that the murderer should have used, as if the murderer had used a silenced pistol, it only took less than ten seconds to kill the two people and quickly leave the scene. As long as the murderer blends into the crowd, he will not be discovered. Xue Hang said lightly.

His words woke me up directly.

Today is Halloween, everyone is dressed in strange costumes, and they don't show their true faces, even if the murderer kills people in front of them, they won't be seen by others.

This can't help but make me think of one thing in martial arts novels along Li Meng's train of thought - disguise technique.

"There were no signs of a fight at the scene, indicating that the killer was either an acquaintance of the deceased or disguised himself as a buyer, and then committed the murder while the deceased was unsuspected." I looked at the environment and said slowly.

After listening to me, Li Meng immediately added: "Since the murderer used a hidden weapon, the secret door must not fight the deceased at close range, he must be standing at a relatively safe distance and suddenly attack the deceased." ”

"Since the scene of the crime is a small store, surveillance must be installed here." After I finished speaking, I looked up and found a small surveillance device in the corner of the cashier at the door.

"This monitoring network is controlled, the mobile phone is the transmission device, and the monitored content can be viewed through the mobile phone. But we didn't have the password for the deceased's surveillance equipment, so we could only take the phone back for the time being and let our colleagues in the Technical Investigation Division crack it. A fellow police officer from the technical team said to us.

I nodded, and after listening to him, I had a bottom in my heart.

Since the murderer is a female deceased who killed at the door, the surveillance video will definitely capture the appearance of the murderer.

With surveillance, it becomes very easy to solve crimes.

After inspecting the scene, the technical team restored the scene, marked the location of the deceased, and set up physical evidence identification plates where fingerprints and footprints were found.

I walked out of the commissary, looked at the waning moon in the sky, and took a deep breath.

There was a long cordon outside the door, and there were more than two dozen onlookers in fancy costumes outside the cordon. They kept looking inside the commissary, whispering something about something.

I pretended not to care, and looked around at the crowd of onlookers, trying to find anyone suspicious among them.

Because in many cases, after committing the crime, the murderer will return to the scene of the crime to satisfy his almost perverted psychology, enjoy the pride of completing the crime, and the thrill of playing with the police.

But today, everyone is wearing very thick makeup, and it's hard for me to see the micro-expressions of the people.

"Team Qin, it's all over." After the technical team completed the investigation of the scene, they put a seal on the glass door to protect the scene, and set up a cordon at the entrance of the commissary.

I nodded, took a deep breath, and said, "Wrap up." ”

It seems that there is no way to relax today's Halloween, criminal police, life is bitter!

By the way, do I really have a Conan physique?!

Back at the Ningzhou Public Security Bureau, the little boy was sitting in the police reception hall on the first floor, and a female colleague was beside him, comforting him softly.

The little boy is much more emotionally stable and can communicate effectively with us.

"What's your name, kid?" Li Meng walked quickly in front of the little boy, crouched down and handed him a lollipop.

The little boy's body subconsciously shrank back, looking at Li Meng with some caution.

"I'm a policeman, don't be afraid, didn't Mom and Dad tell you that it's difficult to find the police." Li Meng said softly, opened the lollipop, and handed it to the little boy.

"That's right, if you have difficulties, go to the police aunt." I also stepped forward and whispered, but I consciously or unconsciously put the word aunt very seriously.

Li Meng glanced back at me, turned his head, immediately changed his expression again, and said to the little boy: "Don't be afraid, I'm a police sister, you can eat candy." ”

"I don't eat, you're bad people......"
